[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] See also Figure 1-Figure 7 A coaxial high-power microwave device structure includes a housing 1, an upper cover 11, a port 12 and a circuit board 7. A fixing seat 14 is slidably provided on the housing 1, a lifting seat 2 is slidably provided on the fixing seat 14, a plurality of guide rods 21 are fixedly provided on the lifting seat 2, a clamping seat 3 is slidably provided on the guide rods 21; a bottom plate 4 is slidably provided on the housing 1, a first inclined block 32 is fixedly provided on the clamping seat 3, a second inclined block 41 is slidably provided on the bottom plate 4, the first inclined block 32 abuts against the second inclined block 41 through an inclined surface, and the clamping A plurality of second springs 33 are arranged between the seat 3 and the bottom plate 4, and the two ends of the second springs 33 are fixedly connected to the clamping seat 3 and the bottom plate 4 respectively; a limiting component is also included, which is used to limit the sliding of the second inclined block 41 after the connection point of the circuit board 7 contacts the port 12. When installing, the circuit board 7 is placed on the lifting seat 2 and the guide rod 21. Under the action of the second spring 33, the second inclined block 41 slides and pushes the first inclined block 32, and drives the clamping seat 3 to slide toward the middle, so as to correct the position of the circuit board 7. After the clamping seat 3 is in contact with the circuit board 7, the second inclined block 41 continues to slide. At this time, because the clamping seat 3 is limited by the circuit board 7, the second inclined block 41 cooperates with the inclined surface on the first inclined block 32 to make the clamping seat 3 move up, the second spring 33 is stretched, and the clamping seat 3, the lifting seat 2 and the guide rod 21 move up synchronously, so that the circuit board 7 contacts the welding point on the port 12. In this process, the position of the circuit board 7 is corrected by sliding the plurality of clamping seats 3 to the middle position, and the circuit board 7 is clamped after the correction, so that the circuit board 7 is more convenient and quick in the process of adjusting and fixing the circuit board 7. Subsequently, the clamping seat 3 is moved up to make the circuit board 7 contact the welding point on the port 12, and the lifting and lowering adjustment of the circuit board 7 is completed, so as to avoid friction or collision between the welding point of the port 12 and the circuit board 7 when the port 12 is installed, resulting in damage. At the same time, the stability of the circuit board 7 during the welding process is improved, and the welding quality of the circuit board 7 and the port 12 is guaranteed.

[0034] Specifically, a hollow tube 31 is fixedly provided on the clamping seat 3, and a telescopic rod 22 is fixedly provided on the lifting seat 2. The hollow tube 31 is slidably connected to the telescopic rod 22. A first spring 23 is provided between the hollow tube 31 and the telescopic rod 22. The two ends of the first spring 23 are respectively fixedly connected to the hollow tube 31 and the telescopic rod 22. By providing the first spring 23, the first spring 23 is compressed when the clamping seat 3 slides. When the circuit board 7 needs to be inspected, the first spring 23 can be reset to drive the clamping seat 3 and the second inclined block 41 to reset, thereby improving the portability during the replacement, inspection and disassembly of the circuit board 7.

[0035] In an embodiment further provided by the present invention, the limiting component includes a tooth block 53 slidably arranged on the clamping seat 3, a tooth rod 42 is fixedly arranged on the base plate 4, the tooth rod 42 is slidably connected to the clamping seat 3, the tooth block 53 is engaged with the tooth rod 42, and when the second inclined block 41 pushes the clamping seat 3 to move upward by cooperating with the first inclined surface, when the circuit board 7 moves to abut the welding position with the port 12, the tooth block 53 is engaged with the tooth rod 42, and the rise of the clamping seat 3 is limited to prevent the clamping seat 3 from excessively rising with the circuit board 7, resulting in extrusion damage at the welding position between the circuit board 7 and the port 12; and, through the sliding connection between the tooth rod 42 and the clamping seat 3, when the clamping seat 3 slides, the base plate 4 slides simultaneously with the clamping seat 3, and when the clamping seat 3 moves upward, the tooth rod 42 ensures the sliding stability of the clamping seat 3.

[0036] The clamping seat 3 is provided with a downward pressure rod 5 for sliding, and a connecting rod 52 is rotatably provided between the downward pressure rod 5 and the tooth block 53. The two ends of the connecting rod 52 are rotatably connected with the downward pressure rod 5 and the tooth block 53 respectively, and the downward pressure rod 5 abuts against the circuit board 7. A third spring 51 is provided between the downward pressure rod 5 and the clamping seat 3, and the two ends of the third spring 51 are fixedly connected with the downward pressure rod 5 and the clamping seat 3 respectively. After the clamping seat 3 moves up and the welding position of the circuit board 7 and the port 12 abuts, the clamping seat 3 continues to move up. At this time, the circuit board 7 is limited by the welding position of the port 12, and the clamping seat 3 and the circuit board 7 are in a relative sliding state, so that the third spring 51 is compressed, the downward pressure rod 5 slides, and the tooth block 53 is slid and engaged with the tooth rod 42 through the connecting rod 52. In this way, the upward movement of the clamping seat 3 is limited by the tooth rod 42 to prevent the clamping seat 3 from excessively moving up, so as to avoid the welding position of the circuit board 7 and the port 12 from being squeezed and damaged.

[0037] Furthermore, a reel 6 is rotatably provided on the fixed seat 14, and a pull rope 61 is provided between the reel 6 and the second inclined block 41. Both ends of the pull rope 61 are respectively fixedly connected to the reel 6 and the second inclined block 41, and are wound around the reel 6. The pull rope 61 is reeled up by rotating the reel 6 to make the second inclined block 41 slide, and the sliding and upward movement of multiple clamping seats 3 are completed synchronously, so as to facilitate the correction and clamping of the circuit board 7, and make it contact with the welding point of the port 12.

[0038] Furthermore, a limit tube 62 is fixedly provided on the reel 6, a rotating member 63 is slidably provided on the limit tube 62, a friction plate 13 is fixedly provided on the outer shell 1, the rotating member 63 is in frictional contact with the friction plate 13, a fourth spring 64 is provided between the reel 6 and the rotating member 63, the two ends of the fourth spring 64 are respectively fixedly connected to the reel 6 and the rotating member 63, and the rotating member 63 abuts against the friction plate 13 under the action of the fourth spring 64 to complete the fixation of the reel 6. When the reel 6 is rotated, the rotating member 63 is pulled to stretch the fourth spring 64, and the rotating member 63 is separated from the friction plate 13, and the rotation of the reel 6 can be completed by rotating the rotating member 63.

[0039] In an embodiment further provided by the present invention, the height of the clamping seat 3 is lower than the lifting seat 2, and a silicone pad is fixedly provided on the lifting seat 2, and contacts the circuit board 7 through the silicone pad. During the rising process of the clamping seat 3, because the height of the clamping seat 3 is lower than the lifting seat 2, the circuit board 7 does not contact the bottom of the clamping seat 3 under the support of the lifting seat 2. At this time, the side of the circuit board 7 is clamped by the pressing rod 5 on the clamping seat 3. After the circuit board 7 slides and rises with the clamping seat 3 to abut against the welding position of the port 12, the circuit board 7 does not continue to move up under the abutment action of the welding position of the port 12. At this time, the lifting seat 2 continues to move up, and the pressing rod 5 5 slides relatively with the clamping seat 3. At this time, the pressing rod 5 makes the tooth block 53 engage with the tooth rod 42 through the connecting rod 52, and the upward movement of the clamping seat 3 is restricted by the tooth rod 42 fixed on the bottom plate 4, so as to prevent the clamping seat 3 from excessively moving upward, resulting in extrusion damage at the welding place between the circuit board 7 and the port 12; and after the welding place between the circuit board 7 and the port 12 abuts, when the lifting seat 2 and the clamping seat 3 move upward at the same time, the lifting seat 2 moves upward because the circuit board 7 does not move, and the upward movement stroke of the lifting seat 2 is compensated by squeezing the silicone pad, so as to prevent the lifting seat 2 from generating excessive pressure on the circuit board 7 and causing deformation of the circuit board 7.

[0040] As mentioned in the present invention, the circuit board 7 is clamped by the clamping seat 3, which is achieved by the lower pressure rod 5 slidably arranged on the clamping seat 3 abutting against the circuit board 7. After the circuit board 7 abuts against the welding point of the port 12, the third spring 51 is compressed, and the circuit board 7 fits with the bottom of the clamping seat 3 to improve the clamping stability of the circuit board 7.

[0041] Working principle: during installation, the circuit board 7 is placed on the lifting seat 2 and the guide rod 21, and the rotating member 63 is pulled and rotated. The rotating member 63 rotates with the reel 6, and the rotation of the reel 6 will reel up the pull rope 61. At this time, under the action of the second spring 33, the second inclined block 41 pushes the first inclined block 32 and drives the clamping seat 3 to slide toward the middle. During the sliding process, the circuit board 7 is aligned and the circuit board 7 is clamped by the pressing rod 5 on the clamping seat 3. Because the height of the lifting seat 2 is higher than the clamping seat 3, at this time, the circuit board 7 does not contact the bottom surface of the clamping seat 3. At this time, the alignment and pre-clamping of the circuit board 7 are completed, and then the port 12 is installed on the housing 1, and the welding point of the port 12 is located above the circuit board 7. Then, the rotating member 63 is continued to be rotated to make the reel 6 reel up the pull rope 61 and pull the second inclined block 41 to slide. At this time, the sliding of the clamping seat 3 is restricted by the circuit board 7 and cannot continue to slide toward the middle. Under the pulling force of the pull rope 61 When the second inclined block 41 slides, the second inclined block 41 cooperates with the inclined surface of the first inclined block 32 to make the clamping seat 3, the lifting seat 2 and the guide rod 21 slide and rise upward. After rising to the point where the circuit board 7 contacts the welding point of the port 12, the rise of the circuit board 7 and the pressing rod 5 is restricted. At this time, the lifting seat 2 continues to move upward to press the silicone pad, and the clamping seat 3 continues to move upward. The second spring 33 is compressed, and the clamping seat 3 and the pressing rod 5 slide relative to each other. In this process, the tooth block 53 slides and engages with the tooth rod 42 through the connecting rod 52. The engagement of the tooth rod 42 with the tooth block 53 restricts the upward movement of the clamping seat 3, thereby completing the restriction of the sliding of the second inclined block 41 and the rotation of the reel 6 and the rotating member 63. At this time, the rotating member 63 can be released. Under the action of the fourth spring 64, the rotating member 63 is in friction contact with the friction plate 13 to complete the fixation of the reel 6. Subsequently, the welding point of the port 12 and the circuit board 7 are welded, and then the top cover can be installed.

[0042] When replacing and overhauling the circuit board 7, pull the rotating member 63 to disengage it from the friction plate 13, and reverse the reel 6 through the rotating member 63, loosen the pull rope 61, and under the action of the first spring 23, the clamping seat 3 first slides open, and after the lower pressure rod 5 disengages from the circuit board 7, the lower pressure rod 5 is reset under the action of the third spring 51, the tooth block 53 disengages from the tooth rod 42, and under the action of the second spring 33, the reciprocating seat descends and resets.

[0043] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
